JOHN M. OBRIEN, OF GLOUCESTER, MASSACHUSETTS.

LIFE-ROPE FOR VESSELS BOOMS.'

SPECIFICATION forming part of Letters Patent No. 359,028, dated March 8.1887.

Application filed August 4, 1886. Serial No. 210,024. (No model.)

To (LZZ whom, it may concern:

Be it known that I, JOHN M. OBEIEN, a citizen of the United States,residing at Gloucester, in the county of Essex and State ofMassachusetts, have invented a new and useful Life-Rope for VesselsBooms, of which the following is a specification, reference being had tothe accompanying drawings, in which- Figure 1 is a side view of boomwith liferope attached; Fig. 2, a top view of boom with life-ropeattached; Fig. 3, a section of boom, showing outrigger.

Similar letters refer to similar parts throughout the several views.

The band E, with bail G and the footrope O, are attached to most booms,and form no part of my invention. The foot-rope O is generally hung soas to fall some distance below the boom.

The person furling or reefing the sail stands upon the foot-rope O andkeeps himself from falling into the water by clinging onto the sail,which is often blown against him with suflicient force to break hishold.

The object of my invention is to render the process of furling andreeling sails on booms from foot-ropes attached to the booms (which inrough weather is extremely dangerous) comparatively safe, by providing arope to lean against when furling or reefing, and something to catchonto when the hold on the boom or sail is broken by the act-ion of thewind or sea.

I attain this object by means of the rope A, attached to the end of theboom' and to the outrigger B. The outrigger is fastened to band E byscrewbolts in such a way as to swing backward and forward. When theOutriggers are horizontal with boom, ropes A are drawn taut, arelevel'with the boom, and will cross the back of a person standing on thefoot-rope beneath the shoulders.

Outriggers are made to turn on bolts, so that when the life-ropes arenot in use they will fall out of the way, the weight of the ropesdrawing the Outriggers backward against the side of the boom.

The Outriggers are drawn into and kept in a horizontal position withreference to the JOHN M. O BR-IEN.
